TO ALL WHOM IT MAY CONCERN: I Be it known that I, ALFRED B. BEAUMONT, ofGrand Rapids, in the county of Kent, and Sta-te of Michigan, haveinvented a new and improved Broadcast Sewer; and I do hereby declarethat the following is a full, clear, and exact description thereof,which will enable those skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification.

The nature of this invention consists in constructing a centrifugalbroadcast-sowing machine with mechanism 3 egulatingthe supply of theseed or grain, andother parts perfecting the whole.

Figure v1- is -a top view of ni y invention. Figure 2 is. a verticalsection of same through the linear a, fig. 1. Figure 3 is a detail viewof the feed-adjuster 6 b, fig. 6, when'seen from beneath. Figure 4 is adetail view of scattering-wheel at c c, fig. 6, with a part of the topdisk r'emoved. Figure 5 is the bevel-gearing, showing thecoupling-device. I Figure tiis an enlarged view of the section throughthe hopper. Similar letters of reference indicate corresponding parts.In a general description of the parts- I A isthe box or body. B, thewheels. 0, the shafts. D, thehopper. I v F, the bevel-wheel or pinion,which is coupled to the hub of, the wheel B, in a' mannerhereinaftershown. This gears into another pinion, G, carrying'a pulley, H, shown atfig.f 5. I This pinion works upon a. vertical pin in the body of themachine, its lower end being in the axle z. Thus the motion of thewheels is communicated to the pulley H, which transmits the some througha belt or chain, :1, to a small pulley, E, on the shaft ]2 of thescattering-wheel i. v

The hopper D has an openingat its hase,'which admits the-graiu into thescattering-wheel beneath, whence the grain is thrown out radiallythroughopenings 'in the said wheel. v

This scattering-wheel consists of two disks separated by radial strips,g, fig. 4, which, with the two disks, form channels, 0, for dischargingthe grain. I

The lower disk is entire, with the exception of the hole for the shaftit, but the upper disk has a large central opening for receiving thegrain into the interior of the wheel, as shown at k k, figs. 4 and 6.

By referring to fig. 6, asectional view of all the parts withip andconnected with the hopper D is shown. 'This hopper is firmly bolted ontothe end or hind gate of the body A, having a cross-picce,j, whichfurnishesthe upper bearing of the shaft 'of the scattering-wheel. I

The lower bearing is shown at lffig. 2, in a cross-piece forming a partof the body of the machine.

Upon the shaft h is seeureda cone, K, the office ofwhich 'is to guidethe grain to the holes in adisk hereinafter described, provided withradial arms, m, which pass, without contact, the arms n, projecting fromthe inside of the hopper. I I I The base of this cone. is a. circularmetallic disk mounted on the shaft h, and extending across and with easycontact of its perimeter, closing the throat ofthe hopper. I

This disk is seen in fig. 6, at k, and is perforated with oblongopenings, which are also shown in fig. 1.

These openings extend all the way around. I

The throat of the hopper is fitted with a metallic bottom, lo, and hasits vertical or cylindrical part, 12, slightly flared at the top t oretain it in place in the throat of the hopper. I I

This bottom, It", is perforated witha series of holes near itsperimeter,said holes reaching only half way round-the same. I I

By means of its flared cylindrical sides, this bottom can rotatepartiallyvwithin the throat of the hopper, an arin, m", being placedon-the same- I The object of,this partial rotation is to bring the saidholes over or away from similar holes in another disk, k, indicated infig. '6 by the red line b b', and-shown in detail at it"l, fig. 3. Ithas an arm, 'm'.

In this figure the diskk is shown from beneath, and it is providedwithratchet-teeth, it, half way. round its perimeter, for a purpose to beshown. i

The arm m" being shown connected with the slotted arm m', belonging tothe disk k, with a set-screw and spring, also to be explained.

A stop, 8, fits into the notches n" on the disk 7c" also to beexplained.

The operation of these three disks is as follows: i v

Motion is communicated to the shafth by means of the belt (I and pulleyE. The cone 7: revolves, and also the first disk 7:. The grain, guidedby the cone, passes down'through, the aforesaid oblong holes in the disk7c and falls upon the disk it, when, if the holes in k" are partially orfully open, it passes into the scatteringwheel 2', and by thecentrifugal action of the latter is thrown out radially.

The arm m on the disk 7c" is in juxtapositioh beneathvthe arm m-von thedisk is The arm m is provided with a slot, 1/, spring, v, and set-screw,'u, to keep thetwo disks stationary when the holes in each are adjusted,for thc'spring o bears against the arm at" on one side, and thesebscrewofibearsagain'st iton the other, thus holding the two arms stationary,and consequently the disks, tolwhich they bBlOliO'.

This device is thus a gauge toregulate the flow of grain, by keeping theholes in the disks 4c" and 70' adjusted with each otherr The set-screwprevents the rotation of the disk 70 in one direction only, which is thedirection of the serrated teeth on'the disk It, but in thereversedirection the said'disk can move against the'spring o, and is heldonlyby the tension of said spring, whichallows it suilioient movementtoc ompletcly remove its-holesfrom coin'cidence'with those of the disk70", thus partially or wholly shutting oifjthe supply of grain, ifdesired, arter this device a given quantity can be sown peracre withaccuracy, orl thefeedof the grain can be adapted to the fast or slowpace of the horse drawing the machine.

Another movement of the disk k is producedat w'll by the driver, bymeans of a roil, M, figs land 2, which is connected with an arm, N, on ashaft, L, to which-is attached a vertieallever, 1?, working by the sideof the 'drivers seat S. v, v v i p This rod M is provided with a spring,S, which is contraeted with the forward movement of the'leverP.

This forward movement of said lever and its rodllf' causes the hook itto catch intoa'tooth on'the disk is, and thus partially rotate thesame-againstthe tension of the spring vl on the arm m of the disk k,acting against the 'arm m" bf the disk It", and thus the disks arepartially rotated till their holes partially or fully pass each other,which. produces a partial or complete closing'of the same. i

When the lever P is liberated, the spring Searries the rod M back to itsnormal position, in which position the hook t is clear from and' not incontact with theratchet teeth of the disk is.

Thus, by moving the lever P forwarder backward, the holes in the disksare closed'orj opened respectively,

andthe discharge of the grain regulated at the will of thedriver, andindependent of the gangebeilore described as thefspriug 12' operates tobring the. holes'lof the disks into coincidence, when .the lever P, withits rod and hook, is liberated or moved partially backward. I i

There is a stop, S, attached to a plate, S, on the bottom D of thehopper. V

This stop has a pointed end, which fits intoV-shaped notches, a, on theperiphery of the disk 70', having for its object 'the adjustment of thetwo disks, with reference to the point of discharge of the grain fromthe wheel, for if it be found that the wheel is discharging the graintoo much to the right or left, the two disks can be rotated to the leftor right, their holes brought to deliver the grain into the channels 0at such a'pcint as will counteract the objectionable tendency aforesaid.i

This is operated by hand, and the simplest form is that of the pin Smoving in and out in a slot'madeiu the plate 8, which plateis screwcdtothe .bottom,'l)', as before mentioned. p

The holes in the two disks being in the front half ofthe same, the'grainisdepositcd into thetscatteringwheel in one half of its channels 0,, andthis being thrown out to the rear of the machine, .none of the grain isthrown forward under the wheels, as would be the case if the whole ofthe channels were fed witlrth e grain at the same time. 7

The bevel-gearing, shown at fi 5, has one wheel,G,-attached within thepulley H, which it drives, both being on ayertical shaft having itsbearings'in the frameand floor of the body of-the machine.

Thewheel F works freely on a reduced part'of the axle X, fig. 5, and ison the same centreof rotation with the running-wheel B and aratchet-disk, nowto be described. I

Working with easy contact by the side of the bevel-wheel F is thisratchet dis'kf, having on its periphery two ratchets f, to catch againstthe pawls f pivoted to the face of .the bevel-wheel F, and provided eachwith a small spring, to hear them down upon the ratchet-'diskf, so thatwhen the motion of the scattering-wheel is accelerated, by its ownmomentum, beyond the proportionate speed of the wheels -13, it will turnwithout hindrance, and no strain will come suddenly upon the-belt dorthe gearing, from any sudden stoppage of the forward movement of themachine. I f i The machine can thus be backed, also, withoutcommunicating motion to the scattering-wheel or gearing, as-in thisreversed motion the pawls will slip over in the manner common withrat'chets.

When the machine is transported from place to place, it can be thrownout of gear with the scatteringwheel and its connect-ions, by liftingthe pawlsff", and securing them above the ratchet with small screws, sothat they will not engage with the said ratchct disk, thus leaving thewheel F torslip freely on its axis, the pawls f" slipping over theratchet-teeth f. v

In fig. 5, the hub 13' is shown partly withdrawn from its axle, thebetter to exhibit. the clutohesft' on the face of the ratchet-wheel andthe corresponding projections 6 on the proximate face of the hub B",which when the hub is in its properpiace, its projections b will be incontact with the clutchcsf', and, either in a forward or backward motionof the wheel, will impinge on the said clutches or projectionsf Thereare two of thes e projections on the diskf, and two on thehuh B, and areplaced near the perimeter of their respective faces, and form a speciesof coupling for transmitting the motion from the hub to the disk, forwhen the former is rotated, its projections, impinging against those onthe disk, rotate the latter, and with it the bevel-wheel F, by means ofthe aforesaid pawls f and ratchetteeth f.

This will be the case only in the forward motion of the hub. In thebackward motion of it the pawlsf" will slip around on the periphery ofthe diskf, and thus commdnicnte no motion to the bevel-wheels, asbei'orementioned.

The bevel-gears, the belt d, pulley E, and scattering-wheel z', areunderneath the bottom, d, of the body of the'machine', as shown in figs.1 and 2. The rod M, and its spring S, are protected from the load ofgrain in body A of the machine, by a box, c Z",'

shown with its side removed infig. 2,.and shown with its top removed infig. 1.

I The circular block z,-in the centre of the scattering-wheel, is placedthere for the better attachment of the scattering-wheel to its shaft. Itforms a part of the wheel, and has a square hole, to fit a squaredportion of theshaft 7t.

I The end and object of this broadcast-sewer are not esclusively thesowing of grain. Its devices are contrived also with a view of supplyinganother want of agriculturists, which is the sowing of plaster and otherfertilizersi and the hopper .D and cone K are providedzwith the arms onand 11., before described, for the purpose of loosening up the plasteror any fertilizer, and preventing the same becoming bedded or packedbythe jolting cf the machine orxthe s'uperincumbent weight of the materialitself. The arms also serve to break-up any clods or accretions in thefertilizing-mammal.

The practical proportional structure of the machine admits of anexceedingly narrow gauge'in its runninggear, and-the wheelsB may beplaced on an axle of four feet or, less,'thus permitting them to passwith facility over rough ground, and from the proximity ofits wheels, itcanbedrlven between stumps and other irregularities ofthesurfaceflthereby avoiding the shocks and concussions incident to thewider machines under similar "circumstances.

3 exhibits .thejdisks' working on the shaft k, the stop and armsprovided with spring-slot and set.

screw, together with the notches in one disk and the ratchet-teeth onthe other, and the rod M, with its hook, catching oh said ratchet-teeth,thus connecting it with the driver;

This device, working inthe throat of the hop-per, and over the centreofthe scattering vheel, thus affords a simple adjustable feed or gaugeto regulate or entirely shut oil the supply of grain orfertilizing-material at the will of the driver.

The semicircular arrangement of the-holes in said disks, delivering thegrain or plaster into thc scatteringwheel at the place whereit is foundmost desirable, and the stops" for adjusting such delivery, workingunder a plate, 8', screwed into the wooden bottom, D, of the hoppeigconstitute import-ant'features of my machine.
